I think I finally improved the "Siren" sound effect (That's what I call it, I don't know what the actual name of the effect is). I had to first create the sound on a Groove Machine Synthesizer, record the LFO and export it as a .wav, slice the audio to make a single note, lower the pitch and frequency, add a slight fade into the sample, and then turn the new audio sample into a DirectWave instrument.

What preset was that?

It' not a preset that you can just get, it's one I had to make myself. I can send you the sample I fixed from it if you want. All I know is that the original I tried to replicate is a sound from either Nexus or Serum.
